If you’re thinking about adding some triple glazing to your windows at home, you probably have a lot of questions. What are triple glazed windows? How much does triple glazing cost? What are the differences between triple glazing and double glazing? We will answer all of your questions and more below.

What are triple glazed windows?

First things first, you need to understand what triple glazed windows are. You likely already have some sort of glazing on your windows without even knowing it! Another common form of glazing is called double glazing. It simply means that there are two panes of glass.

Triple glazing means that there are three panes of glass. These extra layers of glass work as a type of insulation to keep the elements out of your home. If you live in a climate with harsh winters, these extra layers are essential.

How does triple glazing work?

You’re probably used to adding a few extra layers of clothing during the winter months, and triple glazing works the same way. However, these layers of glazing work much better than an extra sweater or two! The difference here is that not only are more layers of glass added onto your windows, but there are also small gaps strategically placed between each pane of glass.

These gaps are then filled with air or a substance called argon, which is an insulating type of gas. Argon is heavier than air, making it even harder for heat to escape out of the window.

Triple glazing also features some other benefits! The extra pane of glass will block out any noise disturbances, are much harder to break, and can even add more value to your home.

But, before you install your triple glazed windows, make sure that the frame of your home can withstand the extra weight. You don’t want to install a triple glazed window just to be left with your house falling around you!

The cost of triple glazing

Now that you know how triple glazing works, you probably want to install them in your own home. But how much will it set you back? That’s an honest concern. To be frank, triple glazed windows cost more than double glazed windows.

To give you an idea, a standard installation of double glazed windows will typically cost around £465, while triple-glazed windows will typically cost £565. Keep in mind that the cost is just for one window.

In general, prices will vary depending upon which type of window you choose, as well as the size and the style of the window. You’ll have to take a look at your home and determine these factors before you head to a company for a price quote.

Here is a general idea of what you can expect to pay depending on the size of your home:

Single-family flat:

2 bedrooms with 4 windows: £1,940

Terraced home:

2 bedrooms with 5 windows: £2,425

Semi-detached home:

2 bedrooms with 7 windows: £3,395

Semi-detached home with more windows:

3 bedrooms with 9 windows: £4,365

Detached home:

3 bedrooms with 12 windows: £5,820

Detached home with more windows:

4 bedrooms with 15 windows: £7,275

So, as you can see above, if you have a large detached home with a lot of windows, the cost of triple glazing can be high. But, there is another thing that you should be aware of: the more windows you get triple glazed, the less expensive each window will cost. In some ways, the more triple glazed windows you install, the better!

The advantages and disadvantages of triple glazing

Like with any home improvement project, there are several pros and cons of triple glazing. Let’s take a closer look at the advantages and disadvantages of triple glazing:

Advantages:

  • Help with noise reduction
  • Enhance home security
  • Cost-efficient
  • Help to prevent heat loss

Disadvantages:

  • Costly
  • Your return on investment will take a long time
  • Can cause structural damage to your home due to weight
  • Blocks light from coming into your home

Is triple glazing worth the cost?

You’d be surprised at how much glazing can help you save on energy bills, which is one reason why triple glazed windows are worth the investment. If your double glazed glass window panes have withstood years of wear and tear, you could seriously benefit from triple glazed window panes. When your glass windows aren’t properly insulated, you’ll find that your heating bills will be higher due to heat loss.

You could probably skip triple glazing for now if you recently put double glazed windows into your home. If you want to be sure that your windows prevent heat loss, try buying a set of heavy curtains to help keep your heating bills low. You may also consider adding secondary glazing to your double glazed window panes.

The differences between triple glazing and double glazing
By now, you may be confused over the difference between triple glazing and double glazing. You already know that a triple glazed window can cost more than a double glazed window, but what are the other major differences?

Thermal efficiency

The number one benefit of glazing your windows is that you’ll be able to keep your home heated without high energy bills. Triple glazing windows are much more effective than double glazing windows when it comes to thermal performance and efficiency.

You can figure out the energy efficiency of a window by determining its U-value. The lower the U-value, the more energy efficiency you can expect from it. Double glazed windows usually have a U-value of around 1.6, while triple-glazed windows boast a U-value of 0.8. The difference here is important!

When you upgrade your double glazed windows to triple glazed, you’ll immediately see the benefits reflected on your heating bill. Triple glazed windows earn an energy rating of A++, which is the highest rating in general. And, who here doesn’t want to get a good energy rating?

Noise reduction

You’ll also enjoy increased sound insulation if you invest in triple glazing! This type of glazing could be beneficial for those of you who live on a noisy street and struggle to sleep with all the excess sounds. Triple glazing has an added layer that double glazing just doesn’t have. All of these extra layers come together and make it difficult for noise to pass through the glass.

Let’s look at the science of it all. Vibrations actually create sound, and when these vibrations hit the multiple panes of glass, the vibration softens. Triple glazing will block most, if not all, sound vibrations that try to get through, meaning you’ll enjoy a quieter home environment. Both double and triple glazing will help with this, but installing triple glazing is your best bet for effective noise reduction.

Security

Yet another benefit you’ll enjoy from glazing is increased home security. Again, double glazing can be helpful, but if you want to feel extra secure, you’ll need the protection that triple glazing can provide. Think of it as adding another layer of protection to your home, loved ones, and your prized possessions.

Light transmission

Because triple glazing can prevent noise and intruders, it can also, unfortunately, make it difficult for light to pass through your windows. Installing triple glazing windows means that your rooms may feel a bit darker.

A simple way to prevent this is to skip the triple glazing on your north-facing windows. That way, you’ll still be able to enjoy the extra protection from noise and intruders while also letting the light shine through in some of your windows.

Double vs. triple glazing cost

Now, to the question on everyone’s mind, what is the cost difference between double and triple glazing? As you may have noticed, there are a lot more benefits to triple glazing. But, that being said, the triple glazing cost will be much higher than the double glazing cost. Here are a few triple glazing cost comparisons to give you a better idea:

Glazing cost of a 1000x500mm white uPVC window:

Double glazing: £272.80

Triple glazing: £327.36

Glazing cost of a 1200x1200mm white uPVC window:

  • Double glazing: £354.20
  • Triple glazing: £425.04
  • Glazing cost of a 1000x500mm woodgrain uPVC window:
  • Double glazing: £368.28
  • Triple glazing: £422.84

Glazing cost of a 1200x1200mm woodgrain uPVC window:

  • Double glazing: £478.17
  • Triple glazing: £549.01

As you can see, there is a substantial difference in glazing cost between triple glazing and double glazing. You’ll have to study these figures, determine your budget, take a look at the pros and cons, and decide on your own if the high price is worth it.

All in all, both double and triple glazing will help to insulate your home, prevent noise, and protect you from potential intruders. We may be biased, but we believe that the benefits of triple glazing outweigh any cost concerns! But, of course, it’s up to you to decide if the cost of triple glazing is worth it.

To sum things up, you’ll enjoy greater thermal efficiency, noise reduction, and security by installing triple-glazed windows. You’ll benefit from more light penetration and a lower cost with double glazed windows. The choice is yours!

Which company should you choose?

Now that you’re settled on installing triple glazed glass windows, your next step is to determine which company you should choose. You have basically two choices: a large national company or a small independent one. There are advantages and disadvantages to both.

You want to be sure that whichever company you choose is registered with both the Fenestration Self-Assessment Scheme (FENSA) and the Glass and Glazing Federation (GGF). If a company is registered with both organizations, you know that you’ll be getting the best quality work for your money. Remember: triple glazed windows cost quite a bit, so you’ll want to make sure you’re working with a trustworthy company.

Let’s compare a few large national companies with a local one:

Anglian Home Improvements:

  • Percentage of customers who felt pressured by the company to sign a contract after a price quote: 42%
  • Percentage of customers who were satisfied with their installation experience: 98%
  • Trustpilot rating: 4.1/5

Everest Home Improvement:

  • Percentage of customers who felt pressured by the company to sign a contract after a price quote: 37%
  • Percentage of customers who were satisfied with their installation experience: 94%
  • Trustpilot rating: 4.3/5

Local company:

  • Percentage of customers who felt pressured by the company to sign a contract after a price quote: 21%
  • Percentage of customers who were satisfied with their installation experience: 91%

Trustpilot rating: will vary per company

As you can see, even when potential customers were pressured to sign a contract with a larger company, they were still nearly 100% satisfied with the job. The same goes for local companies, without as much pressure.

There is also only a slight difference between the percentage of satisfied customers who went with a larger company compared to those who decided to stay local. It should be reassuring to know that, even with a small company, over 90% of customers were satisfied!

Most people who opt for local companies prefer going with the little guys for these reasons:

A local location is convenient

Local companies don’t pressure customers to sign a contract
The company has good reviews and a good reputation
They had already heard good things about the company
They prefer local companies in general

Ultimately, you’ll have to decide which kind of company you’d like to work with. You’ll want to be aware of each option’s triple glazed windows cost before you make any rash decisions, of course.
